NDIR Refrigerant (HFC) Gas Sensor, 0~100%LFL

Refrigerant gas sensors typically use non-dispersive infrared (NDIR) or electrochemical principles to determine refrigerant gas concentration by detecting the absorption of infrared light of specific wavelengths by refrigerant molecules or the electrical current generated by chemical reactions between electrodes. NDIR sensors offer long life and high stability, while electrochemical sensors are more sensitive and suitable for low-concentration leak detection. They can quickly identify different refrigerants, such as R134a, R410a, and R32, helping to ensure the safety and energy efficiency of cooling systems.

Over long-term use, refrigerant gas sensors may lose sensitivity due to temperature, humidity, dust, and environmental influences. It's generally recommended to calibrate the gas sensor every 6 to 12 months, using a standard gas for comparison to ensure measurement accuracy. For routine maintenance, avoid prolonged exposure to high refrigerant concentrations or corrosive environments, and maintain good ventilation. Some gas sensors support automatic zero calibration and temperature compensation, which can effectively extend their lifespan and improve reliability and stability.

Refrigerant gas sensors are widely used in heating, ventilation, and air conditioning (HVAC), cold storage, refrigeration equipment, commercial supermarkets, data centers, and automotive air conditioning systems. Their primary function is to detect refrigerant leaks to prevent degradation of refrigeration system energy efficiency or environmental pollution and safety hazards caused by leaks. With stricter environmental regulations and the use of new refrigerant alternatives, the demand for detection has increased. Therefore, gas sensors have become essential safety and maintenance tools in various refrigeration systems.
